Dappled forests spawn in already explored places.

The problem:

Dappled forests spawn in already explored places which is anoying when it spawn all around your builds and it destroy the environment because they generate in weird random patern with hard cuts offs where dappled trees are cut in half.

The intended feature causing this:

Minecraft Bedrock doesn't save all chunks inside the render distance, instead it saves only modified chunks (where you broke or places something.) which is good for reducing saves size but is terrible for updating your world like you just saw.

My solution to never get this issue again:

Instead of saving only modified chunks, we save chunks in an area of let's say 128 block (8 chunks) around the modified chunks and 128 block (8 chunks) around the player(s).

This way you can build knowing the environment around your build won't budge and you can explore your world and see a structure not too far from you and just continue your walk knowing you can get back to this place to explore it whenever you want knowing it will still be here after updating the game.

If there's any problem with my solution please tell me in the comment.
